Diamond drilling within Goderich, Ontario, Canada had soon discovered rock salt along the shoreline of Lake Huron. Much of this discovery was found to have been located at a depth of 1,750 below the surface. At the time much of this claimed area was first stake by a company who became identified as Astrea Company. Limited in 1956. After further outline this deposit it was stated that the rack-salt had extended for a width of 70 feet at the depth of 1,750 feet. With drilling taking place it was also during this time period when the company had changed it's name to Dominion Rock Salt Company, Limited.

By 1957, the company soon had awarded a contract to Cementation Company Canada, Limited. The contract was mainly aimed at sinking a shaft alongside of the harbour, within the town limits of Goderich, Ontario, Canada, and on the shore line of Lake Huron. It was at this time when the shaft was being prepared, and had been designed to be a circular shaft, which was 16 feet in diameter. As the shaft was driven to a depth of 1,940 feet it would also be cemented all the way down to the bottom. In general being it was also stated that the shaft was collared on a narrow sand-bar, and had went through 45 feet of overburden. More so the contracted company had driven steel piles along the rock edge, and after the overburden was remove it would then be cemented into a shaft form. Other procedures had continued to drill, and grout the water bearing dolomite rock formation that was within this deposit zone. Nothing else had occurred during this time of preparing mining operations for future rock salt extractions.

Shaft sinking by Cementation Company, Canada, Limited had continued to sink the No. 1 shaft to a depth of 998 feet in 1958. There was also a massive head-frame that became cemented, and had reach it's own height of 94 feet. Some more work had also been contracted to the Dan Ellis Limited who became in charge of building the surface plant. It was also by the end of that year when the foundation was officially completed, and construction was progressing very well. For the most part it was also stated that the Dominion Rock Salt Company, Limited had wanted to place this project into operation by 1959. At the time it was also stated that mining will be done using the room and pillar methods, and the use of trackless equipment will then be put into operation. Much of the extracted rock salt will then be hauled to the underground processing area, where the rock salt will then be crushed, and screened before being hoisted to the surface. Nothing else had occurred at this time of placing this operation into production stage in 1958.

Another company re-organization had soon occurred when the Dominion Rock Salt Company, Limited had change it's name to Sifto Rock Salt, Limited. At the time it was also stated that the company was considered to be a wholly owned subsidiary company of the Dominion Tar, and Chemical Company Limited. In 1959, the contract for the 16 diameter shaft sinking phase was officially completed on schedule, and had reach a depth of 1,867 feet. Following this development the company had also cut, and station the main level at 1,764 feet. As this had occurred it was also being opened up by extensive excavations of ore-passes. Even the shaft at this time period was completely timber by the end of August of that year. Much of this whole entire operation was shortly after turned over to Sifto Rock Salt, Limited, who had installed the cables, loading pockets, and combination skip cages.

More expansions had also taken place when the two contracted companies had continued to develop the much needed structures. Almost all of this development had included the completion of the mill, and storage buildings, machine shop, stores, change room, hoist building, office, and ship loading facility. There was also some yard work completed within this time period that had consisted of installing railway sidings, and paving the grounds. In addition to this it was also stated that the shipment facilities for boats, trains, and trucks was also accomplished.

Even more equipment was being used within the underground workings, which included 42 by 56 inch single roll impact crusher, an under-cutter that was fitted with one auger drill, and 2 front end loaders of different models, and capacity. Further company statements had also stated that the primary crusher was installed over the ore passes. Another useful piece of machinery known as the Joy Under-cutter had been used to undercut, and drill the salt before blasting it. Most of the blasting was done by the usage of 40 percent stopeite explosives. Much of the blasted salt was then transported by a front end loader to the crusher where it had underwent crushing. Other preparations within this time period were also making sufficient space in order to place Joy a Drill Jumbo, fitted with four drills, and was capable of drilling a face 45 feet high, and 30 feet wide in one set. Transportations of the salt was also being trucked by Diesel Powered, 25 ton capacity trucks to the crushing area. As the mine continues to expand it was also stated that the crusher would be re-located in order to permit the salt to be dumped directly. Some more plans at this time had also warranted the installation of an underground crushing, screening, and storage facility when space is permitted. Mining operation at this mine were also being done by room and pillar methods, which the rooms are 60 feet wide, and pillars are 210 feet square. These rooms had also became advanced during operation by a length of 1,338 feet, and all mining operations had commenced on October, 1959. During this time it was also reported that a total of 90,000 tonnes of salt was hoisted within this year. Nothing else had taken place as the mine was well into production of the much needed salt extractions.

It was by 1960, when Sifto Rock Salt, Limited had once again went under a name change as it was now incorporated as Sifto Salt, Limited. At this time it was rather reported that the room, and pillar method of mining was being used on the 1,760 foot level. Much of the original headings were considered to have been excavated to 18 feet high, and 60 feet wide. More so it was also stated that the company had increased these heading to 45 feet in height. Almost all of this increase was done when the jumbo drills became place into operation. The pillars within these workings were also being operated at 210 feet squares, which gave a production ration of 40%. Further preparations during this time period had also predicted that the crushing, and screening equipment would be place underground in 1961. Preparations were also being made to permit enough space for this equipment. Salt at the time was also being stored underground when the company had future plans of building a massive conveyor way .

By 1960, the company had also added additional equipment to its mining operation during that year. Most of this equipment had also included two rock wagons, two loaders, an under-cutter, a front end loader, and a Trump Giraffe. For the most part it was also stated that ventilation being achieved by the installation of an additional fan on the surface. Operations of this ventilation unit was strongly able to produce a capacity of 150,000 CFM. In addition it was also reported that the mine air heading unit had it's own capacity of 2,000,000 Btu. per an hour. Besides the much need installations, the company had also extended the workings significantly by 10,389 feet of drifting, and 166 feet of this development was done for ventilation. A huge amount of ore was also hoisted, and milled during this time period, which had totalled 639,440 tonnes. Milling within the Goderich Sifto Salt Mine was being achieved on a daily production rate of 1,752 tonnes of ore a day.

A huge amount of changes soon had occurred in 1961, when Sifto Salt, Limited had commence the development of Shaft No. 2. Preparations at the time were being made so that this shaft did not have any compartments. Other statements had sated that this shaft was also to be concreted lined to it's full depth. Company officials from the Sifto Salt, Limited would decided to not install a conveyance within this shaft operation.

Further excavations soon became completed when the required space was made to relocate the Primary Crusher. With this taking place it was strongly reported that even more installations would occur. Almost all these installations had called for a complete underground crushing, screening, and stockpiling storage for the finished grades of rock salt. Even far more expansions continued when an underground mill was officially developed in an area that measured225 feet long, and 60 feet wide, and was 45 feet high. Another huge amount of lateral development also occurred when a total of 4,918 feet of drifting was done. Milling operations at the Goderich Sifto Salt Mine had milled a total of 729,886 tonnes of salt that came from underground. Production within 1961, had been increased from the previous year of operating, and had totalled 2,433 tonnes of ore per a day. Nothing else had occurred during 1961, as the mine was well into production stage. Contracting of the No. 2 shaft was also given to Cementation Company, Canada, Limited, who employed a total of 9 workers for this project. Cementation Company, Canada, Limited had continued to sink the No. 2 shaft within 1962. It was at this point when the No. 2 shaft operation was officially reaching a depth of 1,417 feet. Much of the No. 2 shaft was designed to be similar to the No. 1 shaft but did not have any compartments, and was 16 feet in diameter. Once the shaft becomes completed it will then be used as an air-way inlet, and an auxiliary escape-way from the mine workings. It was also within this time period when Sifto Salt, Limited, had under went a name change to Domtar Chemicals Limited. Domtar Chemicals, Limited had rather made a division for this operation which was now known as the Sifto Salt Division, Goderich Mine.

In 1962, the production of salt that was shipped from this mine was rather considered to be the highest shipment in history. At the time there was also a program of surface expansions happening in order to provide additional storage facilities, and to increase screening capacities. Mainly this was being done in order to provided an increase to the underground milling facility at the time. Far more construction also occurred in 1962, when the company's contractors had built a salt storage building, two concrete storage silos, and had also increase the height of the screening building by 35 feet. Besides developing the much need structures this company was also able to complete 7,270 feet of drifting. A huge amount of ore also became hoisted, and milled within 1962, and had totalled 1,013,880 tonnes of ore. There was also an increase in production when the mill had a daily capacity of 3,229 tonnes of ore per a day.

The No. 2 shaft was officially completed to its very own depth of 1,835 feet below the collar. With the shaft completed there was also a man-way installed, and had extended all the way to the bottom of the sump. Far more development from underground had connected this shaft operation with the No. 1 shaft at 1,757 feet. At the time there was also no hoisting facilities installed, but there was a lot of room made to provide a hoisting system in the near future for the service cage. Production from the mine was quite similar to the salt that was hoisted from these working in 1962. Even the major development of expanding the surface buildings had also been completed in 1963. For the most part it was reported that construction within 1963, had consisted of an air plenum and heater house over the No. 2 shaft collar. and a new conveyor gallery was constructed from the No. 1 shaft, to the top of the extension of the screening building. Development within 1963, had opened up the workings even more by 8,185 feet of drifting. There was also another huge amount of ore that was hoisted, and milled during the year, which totalled 1,012,500 tonnes of salt. A small decrease in production was also noted as the mill was running at 3,200 tonnes of ore per a day.

Construction within 1964, was rather reported to have been less extensive then the previous years of building additional buildings to store salt. Most of the new additions had became used to store a large tonnage of salt that came from the Goderich Sifto Salt Mine operation. For the most part it was also stated that construction within this time period was mainly aimed at adding additions to the change room, the erection of a heater building, and the installation of the necessary equipment for heating the down cast air in the No. 2 ventilation shaft.

Underground mining operations at this mine had also became improved by the introduction of a new rock-bolting machine. Much of this machine was reported to have been mounted to a 9 tonne crane, with drills, and a basket to accommodate the operator. This boom machine was rather reported to have the capability of reaching the 45 foot high backs, and can also be extended, retracted, and rotated by the operator. In addition it was also stated that the holes are drilled by an auger-type drill, which is activated by a hydrologic motor, and is motivated by a pump driven by the diesel engine. Once the drilling becomes complete its then rock-bolted, and tighten by the same diesel engine that operates this crane.

Company officials from the Domtar Chemicals, Limited had also added a center pivot front end-loader to the underground workings. This machine was also reported to have been fitted with a 3 cubic-yard rock bucket, and is considered to be used for miscellaneous work. It was also stated that this newly introduce loader had performed a much faster action than the older loaders. A small amount of development had also continued to extended the workings by 5,390 feet of drifting. Production from the mine had also hoisted a total of 791,282 tonnes of salt that was milled on a daily rate of 3,000 tonnes. No other development or production had occurred during this time period of operating the mine site.

By 1965, it was reported that the new 966B Rubber Tired front end loader was put into good use. Underground operations continued to extensively blast a large amount of salt that was load onto trucks. Much of this loading was said to have been completed by the 966B Front-end loader. The Domtar Chemical Company, Limited had also added more equipment when a Whiting Model 7TM Track-mobile was put into operation. It was also stated that this new Track-mobile had also help move the much heavier hopper cars within the underground workings. Further planning had also occurred when the company was about to put a head-frame over the No. 2 shaft. This whole entire development procedure would also allow the installation of a friction hoist, running on rope guides. For the most part it was rather stated that all development had occurred on the 1,760 foot main level. During this time period the underground workings became further opened up by 6,810 feet of drifting which became establish. From all development it was stated that a total 1,135,917 tonnes of salt had been hoisted that year. Production from the company's milling facility had also milled 1,330,000 tonnes. Most of this production was also completed at a daily rate of 4,500 tonnes within 1965.

A huge demand for road, and chemical salt had the company placing it new equipment into full service in 1966. It was also rather being studied so the Domtar Chemical, Limited could warrant the purchase for the most suitable mining equipment for salt. Even far more additions became made to the mill when an electronic sorting machine was installed. This whole entire installation was rather made to keep pace with the demand for salt. At the time there was also a huge demand for salt as automatic domestic water softeners became a huge market. For the most part it was also within time period when the project for the No. 2 shaft head-frame was on schedule. Further predictions from the company had also stated that the friction hoist will be put into operation by the following year. Company officials from the Domtar Chemical, Limited had also place an order for the service hoist, and the ropes it had needed. Development within this time period was rather being focus on the mines 1,760 foot level. Almost all of this development had only consisted of 6,140 feet of drifting which became completed. Another huge amount of ore was also hoisted from the underground workings. and had totalled 1,104,506 tonnes of salt. All production from the mill within 1966, had also milled a total of 1,274,000 tonnes.Far more rock salt would also be need in the United States during the harsh winter season of 1967. Much of this large amount of rock salt had also increased underground production significantly. This whole entire purchase had company officials re-stocking all the centers before the winter season came to an end. Almost all production during this time was being heavily achieved by additional rock-wagons, and it's Front-End Loader. Even far more installations became made when the company installed a 110 inch fan at the surface of the No. 2 down-cast shaft. At the time it was also stated that air heating also became increased by installing three natural gas direct fired heaters, with it own combined capacity of 18 million BTU per a min. Some more development also had taken place when a total of 9,625 feet of drifting was done on the main level. The No. 2 shaft was also completed to the hoist level at the 73 foot elevation. By this time the company's workforce of 154 miners had also hoisted a total of 1,400,863 tonnes of salt. From all production the mill soon had process a total of 1,650,500 tonnes, which was achieved at 5,000 tonnes per a day.

It was within 1968, when a new ore-wagon was added to the underground fleet of equipment. The wagon at the time was also equipped with a new suspension system using nitrogen accumulator which provided a smoother ride. By this time the company was also focusing on reducing operator fatigue with these installations made. Other statements had also stated that this type of change would reduce heavy shock loads. There was also new additions made to the underground workings when a large electrical powered ventilation door was installed. Further planning had also insisted on installing another one of these doors in 1969. A huge amount of development had also continued to expand the workings when another 8,847 feet of drifting was done. Even hoisting within that year had also taken a total of 1,467,180 tonnes of salt from the mine workings. In all production the mill had also processed a total of 1,763,200 tonnes of ore that year. Production from the mill was also being achieved on a daily rate of 5,000 tonnes of salt. Some other expansions also became completed that year when the company place No. 2 Head-frame into service. This whole entire structure had also included a shaft house, and a hoisting room that was also place in service. With the structure developed the company would also install a friction hoist that travelled on rope guides. Much of this then became suspended on a tensioning device that's located in the upper part of the Head-Frame.

Even more high demands for production, and shipments had taken place to the export, and domestic markets in 1969. More additions also became made when the company added a new circular storage building that holds 15,000 tonnes of salt. There was also additions made the surface facilities in order to meet demands for salt. These demands also had huge carriers shipping salt products by water from Lake Huron, and continue to do so till this day,

Underground workings in 1969, had been mainly confined to the room, and pillar method of mining. The main faces were also significantly developed, and had reach a height of 45 feet. At the time it was also reported that the rooms, and truck-ways became extended by a width of 45 feet. Further estimations had revealed that 30% of salt was also left within the roof section of the underground workings. Mine production within 1969, was also being achieved at level of 40% in salt extractions. With demands increasing the company was also planning out a large expansion program that would last several of years Much of this planning had been done to increase production from 350 to 500 tonnes of salt per an hour in 1970. Even the company's plant. underground mining equipment, and the workforce will also increase to meet an underground production rate of 2,000 tonnes per a day. Besides expansions the company continued to extend its workings when a total of 14,435 feet of drifting was done. A huge amount of salt was also hoisted from the underground workings, and totalled 1,692,000 tonnes. All production from the mill had also treated a large amount of salt that totalled 2,018,000 tonnes in 1969. The same amount of development, and production would also continue in 1970, and is still being operated to this day.
